>reminds himself that Phil Hartman died in 1998 and they retired the characters dubbed by him (Lionel Hutz and Troy McClure)
>Phil Hartman actually wanted to do a McClure live-action

I wasn't aware of this until recently due to years watching out-of-order reruns so I couldn't pinpoint at which point both of his characters stopped appearing (plus, for non-anglophones, there's also redubbing, so many people might still think Troy's voice and character are still alive and kicking).
